Which of the following points are a critical point of x)? Choose all correct answers. [33: [32: [33:4 [33:4 Suppose f: [53,033] > R is a function with no absolute maximum on [a ,b]. Which of the following must be true? O f has no absolute minimum on [a , b] . O f Tat) does not exist for some a: in the open interval (a, b} . O f is continuous on [a , b] . O f is not continuous on [a , b] . O 3' does not have any critical points in [a , b]
